NOTES:
1) The BCLK frequency must be an integer multiple of the FSC frequency. The maximum BCLK frequency is 8.192 MHz. The minimum BCLK frequency is 64 kHz in compressed mode
2) TSX1 or TSX2 typically delays from the FSC for 8 ∗ N ∗ t22 ns in compressed mode and 16 ∗ N ∗ t22 ns in linear mode, where N is the specified time slot (value of TT[6:0] in register
3) t33 is defined to be the time when the TSX1 or TSX2 output achieves high level.
4)
